Recent work on the autonomous healing in cementitious materialswas reviewed. The development of the fractured process of carriers encapsulating healing agent, the releasing mechanism of healing agent and the characterization of repairing effect related to autonomous healing was introduced from the viewpoint of carrier shape. The influence of the carrier shape on the autonomous healing behavior and the advances on the modeling investigation of amount of carrier required were summarized. The feature and classification of healing agent used in autonomous healing and the environmental factors on the selection of healing agent were represented. In addition, the makeup and the preparation technology of carrier shell were also introduced. Some issues of the future development of autonomous healing in cementitious materials were given and the development trend was prospected.
